Channel number used to identify the active trace
Operands, operators and functions; see table below.
*RST; :CALC:MATH:MEM
Copy the current state of the default trace 'Trc1' to a memory
trace named 'Mem2[Trc1]'. The memory trace is not dis-
played.
CALC:MATH:SDEF 'Trc1 / Mem2[Trc1]'
Define a mathematical trace, dividing the raw complex data
trace by the stored memory trace. The mathematical trace is not
displayed.
CALC:MATH:STAT ON
Display the mathematical trace instead of the active data trace.
